To the Editor: —I believe I have found a simpler method for preparing dichloramin-T than that described on the packages put out by the pharmaceutical houses. My method is: Weigh out amount of powdered dichloramin-T, place in mortar and rub up with small amount of chloroform (carbon tetrachlorid may be used) until all is dissolved, then add chlorcosane to the dissolved dichloramin-T. The chloroform is easily evaporated and thus leaves the dichloramin in solution in the solvent. By this method can be prepared a fresh solution of dichloramin-T in a few minutes, whereas the heat and cold methods take a much longer time. In the heat method, there is danger of overheating, in which a precipitation is caused, which renders the dichloramin-T useless and very irritating. [Comment. —We can see no advantage over the heat method, if the chloroform or carbon tetrachlorid must be removed by evaporation. However, the use |
